Joy Talk is Cheap

This is a project to build a low cost RS232 interface which does not require a PEB. This project appeared in the June and
July 1983, 99er Home Computer magazine. The article was written by Paul Urbanus (now where have I heard THAT name before :>)

Below is a schematic which I redrew, and I have removed all the mistakes that appeared in the orginal printing of the magazine.

The PDF below contains both of the two part articles. You will need a mini-memory cart to be able to use this project.
